Lol! Yeah that's what am doing. Am powering out tha lil that motor has left that's how I know or think is giving out. Idk is its tha compresion but at high speed or at high rpms tha motor studders!

I thought it needed a tune up so I changed everything. Spark plugs, wires, oil and oil filter! Everything and still tha same thing. So then I went for tha coils and changed them out too and still same thing. So tha last thing I thought it could b was tha compresion. 310k on tha engine so am guessing it could b tha seals. What you guys think?



Thanx for tha welcome bro and yes am enjoying my 7!

Did you check fuel? That doesn't sound like a compresion problem.

Well tha fuel filter is new. Idk what else can b wrong with tha fuel system if it would b tha fuel. It doesn't idle bad or anything.
